Specification of Letters Patent.

Patented Mar. 21, 1916.

Application filled July 13, 1915. Serial No. 39,602.

To all 'whom it may concern 'type of scrubber having a central conical mop adapted to fit the interior of the tumbler, and external scrubbing-elements which are hinged at their ends about theV central scrubber and are urged forward toward the central scrubber by an elastic band. Bv

vthrusting the tumbler over the central scrubber or `mop and between the outer scrubbers and then rotating either the tumbler or the scrubber, theinterior and exterior could be simultaneously cleaned.V

A scrubber according to the present invention is provided with hinged scrubbingelements surrounding vthe central mop, the said elements constituting the external wall of the scrubber, so thattheycanA be swung out flat for cleaning purposes.

One ofi'thediiiculties inthe forms of,

scrubbers heretofore employed is that the scrubbing-elements surrounding the mop cannot be got at satisfactorily for cleaning them, but this difliculty is overcome by theV construction hereinafter described.

In the accompanying drawings 1-Figure 1 is a perspective view of a scrubberconstructed according to one method of carryingrout this invention; Fig. 2 is a1 perspective View ofthe same scrubber with the parts opened out for cleaning, and Fig. 3 is a4 side elevation of a scrubber constructed according to a modified method of carrying out the present invention.

The central scrubbing element conveniently takes the form of a cylindrical wooden plug A which is secured to a base B,.for example by providing it with a screwthreaded metal stem A1 which engages a-correspondingly threaded metal socket B1. The plug A is provided over the Whole of its exterior with bristles so that it constitutes a brush which is approximately cylindrical in form and at the top is rounded. This brush is of such dimensions as to fill the interior of the tumbler or other article that it is intended to scrub, and may be variously shaped according'to the interior shape of such article, that shown in the drawings being intended for cleaning tumbler-s having the bottom rounded on the inner side.

The exterior scrubbers take the form of segmentalbodies C which may be of wood charged with bristles C1.y The operative side of each external scrubbing-element is shaped approximately to fit flush against an approximately cylindrical surface and as many of these may be employed as is found convenient, four being shown in the drawingsmountedequidistant around the central scrubber A. Each scrubber C is secured to the base by a hinge C2 and the upper ends of the scrubbers are grooved at Ca to receive an elastic band D. l/Vhen the elastic band isk removed they can be opened out as shown in Fig. 2, so that all parts can be cleaned, and when the band is in position, they'are drawn together toward the central scrubber, so that when a tumbler is pushed in, as shown at E,they are forced back against the yielding control of the elastic bandD and thus bear against the exterior of the tumbler, while the bristles on the inner brush A bear against the interior of the same; thus by rotating the .tumbler by hand it is scrubbed inside and out simultaneously.

Scrubbers have been proposed for simultaneously cleansing the inside and the outside, but the outside scrubbing-elements have been fixed relatively to the inside one and thus if a tumbler was rather too large, or was a little carelessly handled, it was broken between the unyielding scrubbing-elements, whereas the scrubber arranged as described Ayields to the tumbler, so that even if this is not put on quite true to the central element it is not broken easily, and, moreover, the yielding-control insures that the scrubbers are kept up to their work on all sides of the tumbler.

-It will be seen that in the construction shown in Figs. 1 and 2, the lower ends of the scrubbers C being hinged to the base cannot move very freely relatively to the central scrubber A. In Fig. 3 an arrangement of scrubbers F is shown, whereby each scrubber can move bodily to and from the central scrubber.v Each scrubber F is carried by a- U-shaped member or a stirrup G whose ends are bent outward at G1 to form a mouse-trap spring and the extreme ends are driven into or otherwise secured to the base H at G2.

The looped end of each stirrup G is secured to the scrubber by a strap J Within which it freely hinges. It will be seen that each of these scrubbers can tiltabout the bend of the stirriip G, so thattlie base can lie outl farther from the central .brush than the upperend ,when used with an article such asa tumbler 5 the bottom end of which is usually Of smaller vided ontheni such as a pad of wash-leather. 2T he invention, moreover, isnot restricted t0 Y the washing of tuinblers, as lamp chimneys or any ycircular article which provides comparatii ely plain exterior and interior surfaces could be cleanedl by such a device, the

device being shaped according to the Work itV is intended to do. Y Y Y Although scrubbing has been referred to Vthroughout the specification, it Will be understood that this does not necessarily mean scrubbing by means of bristles, as any kind of rubbing surface may be employed for the purpose, according to the character of the cleaning which is desired. 1
